I would assume that regular consumption of burned meat was much more
rare among our ancestors than among us. My message was there simply
to suggest a possible explanation of increase in cancer of the colon
among high meat consumers.

I seem to remember seeing studies that show burned food being carcinogenic.
The best I can remember I saw some references to that in the 'Life
Extension' book, but not sure. Also remember that high intakes of
various vitamins and other nutrients can significantly reduce that
effect.  Again, this is a vague recollection and not meant to be
anything definitive.
